# Config file for Powerlevel10k with the style of robbyrussell theme from Oh My Zsh.
#
# Original: https://github.com/ohmyzsh/ohmyzsh/wiki/Themes#robbyrussell.
#
# Replication of robbyrussell theme is exact. The only observable difference is in
# performance. Powerlevel10k prompt is very fast everywhere, even in large Git repositories.
#
# Usage: Source this file either before or after loading Powerlevel10k.
#
#   source ~/powerlevel10k/config/p10k-robbyrussell.zsh
#   source ~/powerlevel10k/powerlevel10k.zsh-theme
